An antenna truss is a supporting structure that holds an antenna mast upright. A properly designed truss supports the antenna against wind and minor impact. Making an antenna truss for your ham, FM or high definition antenna is often as straightforward as placing a supporting pipe in the ground, anchored by properly placed guy wires for increased lateral support.
When you first looked at the Heathkit or Hallicrafters ham radio kit you got for your birthday years ago, you were hooked. Since then, you’ve probably cobbled more than one piece of ham gear together. Now, you find that you need to switch between two antennas. You can buy an antenna switch box, but if you have some spare bits and pieces, such as coaxial sockets or a junction box, hanging around, you’ll have the satisfaction of having done it yourself, once again. You can even add a frequency counter.
If you would like to have a TV in your work space, but you have limited space, combining a desk with a television stand can provide a space-saving solution.

A television enclosure must be waterproof to prevent moisture from damaging the electronics of the television, and to reduce the risk of fire and electric shock.
Citizen Band radio, CB, is a short-distance radio communications system used by both commercial truck drivers and private citizens. Often, CBs are mounted and used inside vehicles and are a good way to call for emergency assistance in areas where there may not be cell phone coverage. However, there are also CB base sets that can be used from the home too. These base sets use telescoping antenna systems that are mounted outside, which are similar to television antenna used before the advent and widespread use of satellite and digital cable television.
The DK3 screwdriver antenna was originally developed by CB enthusiast Don Johnson in 1991. He designed a CB antenna using a modified electric screwdriver motor installed within the lower section to create a multiband antenna. The lower part of the antenna was built with large-enough tubing to encase the screwdriver, but it also increased the radiation efficiency of the antenna, making it work better. The DK3 screwdriver antenna maintains its superiority, and most CB experts recommend buying Don Johnson's original DK3 antenna design for an already-assembled mast section of the antenna.
GMRS and FRS radio systems are a popular way for people and firms to communicate for small distance without using a cellular or land-based telephone. GMRS, or General Mobile Radio Service, radios run at approximately 1 to 2 watts of power. FRS, or Family Radio Service, radios operate at less wattage and have less of a range. One common way to increase the range in these radios is to use an outside antenna. The key to using this method is designing a beam that is sized and oriented in a way that it serves its function the best way possible.…
J-pole antennas are common in amateur radio service because they're easy to build and perform well. All J-poles are end-fed, half-wave antennas; a short tuning stub gives poles their "J" shape. A simple J-pole is small enough to roll up and carry in a pocket, and it can operate on both the 2-meter and 70-centimeter amateur bands with a handheld transceiver.
A wireless antenna is necessary in order to receive transmissions from a wireless home network that is connected to the Internet. Signals degrade as they travel across distances, which makes interacting with a wireless network from a backyard more prone to failure when the transmitter is inside the house. Build an underground antenna system to amplify and strengthen the wireless signal. Supplies from a hardware shop and an electronics store will be needed, as will tools commonly found in most homes.
Building a credenza is one way to have a furniture item that reflects your style and adds vital storage space to your home. A television credenza can cut down on clutter with its built-in shelves or doors. Because of its small scale, it does not take up the floor space of a bulky entertainment center. Building a credenza requires some carpentry skills, but, as a shortcut, you can use an existing piece of furniture as the frame of a homemade credenza.
A good TV base (also known as a TV stand) is essential to ensure your TV sits upright and at eye level for all viewers. You can build your own TV base out of a few pieces of scrap wood.
Amateur radio antennas, like all antennas, need to be in resonance with their transmitted frequency. In addition to working well on its fundamental frequency, an antenna will also function on even harmonics of the fundamental frequency for which it was designed. The relationship between the 20-meter (14 MHz) band and the 15-meter (21 MHz) band is only 2/3 of a harmonic and is difficult to tune properly. A 40-meter (7 MHz) antenna, however, is resonant on both 20 meters and 15 meters as the second and third harmonics of 7 MHz respectively. Build an inverted V antenna designed for 7…
A folding TV tray can be very useful in the living room, letting you eat in comfort while relaxing on the couch before you fold it up and slide it away in an out-of-the-way space. A wooden TV table goes one better than the traditional metal design. It's not only functional, but also an attractive piece of furniture than can be used inside the house and out in the garden.
Amplitude modulation (AM) radio receivers can use a variety of antenna designs, and one that offers superior reception is the loop antenna. This very simple design can outperform other styles, and is an inexpensive way to extend the range of most AM radios.

TV signals are sent by means of electromagnetic waves. A TV antenna is designed to act as a transducer, which converts electromagnetic waves into electrical currents the TV can then interpret. To this effect, a cheap way of amplifying or strengthening a TV's signal is to create a device that magnifies and focuses these electromagnetic waves. As we're dealing with magnets, which are used in TVs to reduce static interference, a TV signal amplifier should result in clearer picture and sound.
This is a crude yet useful homemade TV antenna amplifier that is much safer and easier to make than trying to construct a complicated amplifier using circuit boards and soldering tools. "Amplifier" here is being defined as a connection that will make your TV reception stronger. Ferrite magnets are commonly used in radios and act as resistors, which means they help stop high frequency noises from entering or leaving electronic devices. So in theory, a "magnetic amplifier" should help to transfer energy from your antenna to your TV more efficiently and control static noises. While this crude "amplifier" may or…
